A microcontroller family from Motorola descended from the Motorola 6800microprocessor. The 68HC11 devices are more powerful and more expenSIve than the 68HC05 family. {FAQ (ftp://src.doc.ic.ac.uk/usenet/usenet-by-group/comp.answers/microcontroller-faq/68hc11)}. There is an opcodeSImulator for the 68HC11, by Ted Dunning . Interrupts, hardware I/O, and half carries are still outSIde the loop. Adding interrupts may require SImulating at the clock phase level.
